Actually, reading Ptichka's translation, it sounds like children were the make or break issue. I can't blame her at all there if that is important to her. That is certainly something that husband and wife must agree upon.
I was so focused on G and G who were my favorites that I don't know as much about M and D. I chiefly remember them for the flexibility. I wish one of them would write a book. I would like to know a lot more about the Soviet Sports system; that was one of the most interesting aspects in "My Sergei" to me.
